In a case where I write a query for dpkg-query to list me some package, I would like it to return me the package name if it finds something. If it doesn't find anything, I don't want it to output: no package found matching {package-name} I would like it to output nothing at all.

The reason for this is because my query is in a script and if it returns that my script breaks. How can I achieve this?


You can redirect dpkg-query's stderr to /dev/null to silence the error message, as in dpkg-query --list <package> 2>/dev/null.
